Key Findings
- 01Dense-phase pipelines exhibit the lowest environmental impacts for CO2 transport, both onshore and offshore, now and in the future.
- 02Even with significant improvements in alternative transport modes (truck, train, barge, ship) by 2100, pipelines remain superior.
- 03A gigatonne-scale CO2 pipeline network's total environmental impacts are projected to be a very small fraction (<0.075%) of Europe's safe operating space.
- 04Trains and electric trucks have the next lowest climate impacts after pipelines.
- 05Batch-wise onshore transport can lead to exacerbated freshwater ecotoxicity, particulate matter formation, and metal/mineral depletion.
Application
Design takeaway
When designing or specifying systems for carbon dioxide transport, opt for dense-phase pipelines as the primary solution due to their superior environmental performance across multiple impact categories.
How to apply
When evaluating transport options for CO2 in a design project, conduct a prospective life cycle assessment to compare pipelines against other modes, considering future scenarios and scale.
Project actions
- 01When researching transport options for your design project, look for studies that use Life Cycle Assessment (LCA) to compare environmental impacts.
- 02Consider the scale of your project; impacts that are small for individual transport might become significant when scaled up.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a prospective life cycle assessment to consider future scenarios.
- +Analyzes a comprehensive set of 16 environmental impact categories.
- +Evaluates impacts relative to planetary boundaries ('safe operating space').
- +Considers large-scale deployment implications.
Limitations
The accuracy of the 'prospective' aspect depends heavily on the assumptions made about future technology and energy sources.
Reliability & validity
The study's reliability is enhanced by using a comprehensive LCA framework and projecting impacts over a long timeframe. Validity is supported by comparing against established environmental boundaries, though the prospective nature introduces inherent uncertainties.
Think critically
How might the 'safe operating space' for environmental impacts change in the future, and how would this affect the conclusions of this study?
Design Principles
"Select transport infrastructure based on a comprehensive life cycle assessment that accounts for future technological advancements and large-scale deployment scenarios."
As the demand for carbon capture and storage (CCS) grows, understanding the environmental footprint of CO2 transport is critical for large-scale deployment. This research provides evidence-based guidance for selecting transport infrastructure that minimizes ecological harm, ensuring that climate mitigation efforts do not inadvertently create new environmental burdens.
What This Means for Your Design
Pipelines are the best choice for moving CO2 because they cause the least harm to the environment, even compared to trucks or trains, and this will still be true in the future.
